To all whom it may concern.-

Be it known that I,ADOLF LUnvIG LoN- NERBERG, a subject of the King ofSweden and Norway, residing at 8 Kungsholmsgatan, in the city ofStockholm, Sweden, have invented certain new and useful Improvements inInhaling Apparatus, (for which patents have been granted in Sweden, No.3,797, dated December 12, 1891, and No. 3,829, dated March 18, 1892; inBelgium, No. 98,992, dated March 28, 1892; in Norway, No. 2,614, datedMarch 23, 1892; in England, No. 5751, dated March 23, 1892; in France,No. 220,576, dated April 1,1892; in Switzerland, No. 4,999, dated April6,1892; in Germany, No. 67,7l7, dated March 22, 1892, and inAustria-Hungary, No. 36,281 and No. 14,082,dated March 12, 1893,) ofwhich the following is a specification.

This inhaling apparatus is principally intended to be used for thecuring of any. afiection of the chest when a certain gas or gases ormixture of gas and air is to be inhaled,'the

apparatus being therefore so arranged that the relation between the airand the gas may be easily regulated. It may, howevenalsoj be used forinhaling air alone, for instance,

when it is desired to'have the air to be inhaled heated or purified.

The apparatus is of such dimensions that the person using same cancarry'itabout: while at the same time the gas is being de-- vote anyattention to the apparatus nor is he inconvenienced thereby.

The apparatus consists essentially of a bottle or vesselcontaining thematerial or.liquid from which the gas is to be generated, absorbed in asponge, or in some solid, porous material, forl instance charcoal, or itmay be in liquid state. Into the bottle there descends a tube, providedwithin the bottle with an adjustable valve, through which the gas canascend the tube, and at the outer end of whichthere is fixed a shieldprovided with valves and intended to be placed in front of the mouth.Through other valves the at- "mospheric air is drawn into the tube orthe; bottle, the'se valves being likewise adyustablev so that the airarrives in the tube and the bottle at the same time in the same or indifferent proportions, or only in one of them at the same time. As tothe passage of the air, this may be arranged in various ways. In theannexed drawings several constructions therefor are represented, whichhowever do not differ from each other materially.

In'the said drawings-Figure 1, is a sectional elevation'of-an inhalingapparatus embodying my improvements. Fig; 2, is a similar viewillustrating another .form of the apparatus. Fig. 3 is a similar view ofanother form. I i Fig. 3 is a sectional plan of the upper part oftheapparatus seen in Fig. 4:. Fig. 4 is a; sectional elevation of anotherform of the apparatus. Fig. 4* is a detail sectional plan the plan ofthe section being through the neck of the generator vessel seen in Fig.4. Fig. 4* illustrates details which will be described.

Referring to Fig.1 A designates a bottle inclosing a sponge, B,-containing the material from which the gas is to be generated. Intothezbottle there descends, through the neck thereof, apipeiO,i,containing a pipe D, which extends'farther'down into the bottleand is closely embraced by the lower end of the pipe .O. I On the lowerend of the pipe D is fitted iazcap, G, provided with a lateral openingH. The latter, through which the gas generated inthe bottle enters thepipe D, can be made elastic collar L, fitted over the neckof the.bottle, and the size ofthe opening E can be regulated by means of anadjustable collar F on the pipe 0. The atmospheric air may likewise belet into the bottle. For-this purpose there is a :hole .A' in the neckof the latter, which hole can be closed or left more or less open bymovinga rubber ring A up;

ward or downward on the neck of the bottle. Finally the top of the pipeD is provided with avalve 1 opening toward the tube. If required to havethe air to be inhaled only slightly mixed with the gas from the bottle,the hole A is closed and the cap G is adjusted so that the hole H issuificiently open. When inhaling, the atmospheric air flows into thetube through the hole E and there suction takes place just as with anordinary ejector in the pipe D. The gas and air are mixed in the tubeand are inhaled through the valve P. The exhalation takes place throughthe valve 0. If the hole H be further opened, more gas will enter thepipe D, and if the hole A be also opened and the hole E closed, the airinhaled will be still more mixed with gas, inasmuch as the atmosphericair, during the inhalation will then rush into the bottle and cause somepressure, wherefore gas and air will flow up into the tube in an activemanner. It is thus possible to regulate the mixing of the air inhaledwith gas with great exactitude.

In Fig. 2 the apparatus is represented somewhat simplified. The tube Mhere descends directly into the bottle through a sleeve-like stopper M,inserted in the neck of the bottle, this stopper being provided with alateral opening as is also the tube, and both of these lateral openingsmay be regulated by turning or displacing the tube and the sleeve inrelation to one another. This regulation can, however, be eifected inmany other ways, for instance by causing the lateral opening of the tubeto project more or less above the top of the sleeve, and the sleeve mayconsist of a pierced cork, or the tube itself may be closely fitted intothe neck of the bottle. Into the lower end of the tubeM there isinserted a small, closed glass tube or cap D, and by pushing this tubemore or less into the tube M, the lateral openings D D of the latter maybe left more or less open. If the tube M consists of such a material asmay be alfected by the contents of the bottle, the end of the sameentering into the bottle may be made of glass. The mouth shield islikewise simplified, as instead of the above described valve P, a smallrubber plate, P, is fixed outside of the shield and covers an opening inthe latter and instead of the valve 0 the small flap O is used insertedin the tube. The shield may be maintained in place in front of the mouthof the patient by elastic string or straps round the head. These are notshown.

Figs. 3 and 3 show the apparatus so arranged that it may be used eitherin the way described, or for heating the airto be inhaled, with orwithout simultaneous mixture with gas. Into the bottle there descendsthe curved end of one or more U-shaped pipes, B, one end of each ofwhich rises through the stopper and the other ends enter into a cham berR in the stopper. A tubular nipple, S, is inserted into the chamber R,and to this nipple is connected the inhaling tube. The

nipple S may be inserted as shown by the full lines, or as shown by thedotted lines; that is, either horizontally or vertically. Adj ustablevalvesa cover the outer ends of the pipes R, and the atmospheric air canalso enter the bottle through another channel a, traversing the stopper,and which can likewise be closed more or less by means of a valve 5.Within the bottle and in the pipes there are holes 0 so that the gasgenerated in the bottle may enter the pipes and pass into the tube. Forpersons suffering from phthisis theinhalation of hot air has proveduseful. This ought then to be so'much the more the case, if the air weremixed with some gas known to act benefically upon the lungs. Theapparatus Fig. 3 is very well adapted for introduction of this kind. Thebottle is placed in a vessel containing hot water or steam so as to beheated. The air passing into the apparatus through the valves a willthus be heated when passing through the pipes and in order that the airmay be speedily heated and as little resistance as possible occur ininhaling, several pipes are inserted among which the passage of the airis distributed. Through valves b the atmospheric air may be let into thebottle with the view already stated.

The form of apparatus illustrated in Figs. 4 to 4 difiers from that lastdescribed substantially only in that both ends of the U- shaped pipe orpipes R pass through the stopper and that the tube M is connecteddirectly to one end .of the pipe. If several pipes be used (the figureshows two) the ends of the pipes may be coupled together by means of abranch pipe 013, Fig. 4 with which the tube M is connected. The oppositeends of the pipes R are covered by adjustable valves a as in Fig. 3 andwithin the bottle there are holes in the pipes so that the gas may enterthe same. The tube Figs. 3 and 4, is provided with lateral openings asat E Fig. 1, in order that the air may pass directly into the same, whenit is not required to let the air pass through the pipes R the openingin the tube being, on the contrary closed, if the air is to go throughthe pipes. The apparatus Fig. 4, may also be used for the inhalation ofheated air and with or without the addition of gas generated in thebottle. If heated air only is to be inhaled one has only to close theholes {0 and the valve 1) so that no gas may enter the pipes and aironly enters the latter. In lieu of the hole A in the neck of the bottleFig. 1, or the channel a, Fig. 3, there can evidently be a hole in thebody of the bottle covered by an adjustable valve plate. Such a valve Ais shown on the apparatus in Fig. 4:. In lieu of the bottle A it isevident any other suitable vessel may be used.

The apparatus described may also be used for purifying the air to beinhaled. The bottle is therefore fitted with a filter, for instance madeof cotton, with or without addition of other material depending upon thetoo nature of the air, and the air is caused to enter the bottle throughthe valves A a and the pipe or pipes through the valves 0. The air willthen be purified during its passage through the filter. In lieu of amouth shield the tube M may be provided with a mouth piece of any otherdescription found to be convenient.

Having thus described my invention, I claim 1.
